A 152 cm tall barrel has a circumference of 56.52 cm.

What is the volume of the barrel using the formula for the volume of a cylinder as an estimate?

Round to the nearest hundredth of a cubic centimeter.

Use 3.14 for the value of π. Note: V = πr2h.

given the length of circumference so you can calcule from this the radius - do you know formula of circumference ?

@ThisGirlPretty

jhonyy9 · Answer

formula of circumference C= 2pi*r 
r is the length of radius

jhonyy9 · Answer

using this can you calcule the value of r ?

jhonyy9 · Answer

courage i m here to help you

jhonyy9 · Answer

hope you know pi=3,14 
yes ?

jhonyy9 · Answer

using these above wrote details you can writing

56,52 = 2 * 3,14 * r

56,52 = 6,28 *r   divide both sides by 6,28

r = 56,52/6,28

r = ?

jhonyy9 · Answer

get the value of pi

given in the text of your exercise that the volume V=pi*r^2 *h

so using these you can calcule easy the volume of barrel

hope helped

@kittybasil please what is your opinion about above wrote ? and how you make to collaborate the asker ?

kittybasil · Answer

uh... what?

kittybasil · Answer

$$V=\pi r^{2}h=3.14\cdot r^{2}\cdot h$$the barrel height is 152 cm and the circumference is 56.52 cm

kittybasil · Answer

I assume you should find the radius $r$ from the circumference?
@dude any thoughts cause I'm bad at this lol

dude · Answer

Yeah

kittybasil · Answer

Okay thanks

Shadow · Answer

$$c = 2 \pi r$$
$$c = 56.25$$
$$56.25 = 2 \pi r$$
$$r = \frac{ 56.25 }{ 2 \times \pi }$$
Solve for r then input into formula for volume
$$V = \pi r ^2$$

kittybasil · Answer

shad they want $\pi=3.14$ tho

Shadow · Answer

Yeah they can do that c;

Okay, so your radius $r$ can be derived from the circumference via formula$$C=2\pi r$$ with $\pi=3.14$

$$C=56.52=2(3.14)r$$$$r=\frac{56.52}{2(3.14)}=9$$
<hr class="bbcode_rule" />
Now we calculate volume from the radius we found:$$V=\pi r^{2}h=3.14(r^{2}h)$$$$V=3.14(9^{2}\cdot152)\approx38660\text{ cm}^{3}$$
